TYPE-WRITER RIBBON ATTACHMENT.

Specification of Letters Patent.

Patented Nov. 26, 1907.

' Application filed February 28.1907- Serial No. 359,756.

- California, have invented certain new and useful Im rovements in Te-Writer Ribbon Attac ents; and L do eclare the following to be a full,clear,'and exact descriptionxof the same, such as will enable othersskilled in the art to which it appertains to make and use the same,reference being had to the accompanying drawings, and to the charactersof reference marked thereon, which form a part of this specification.

' This invention relates to improvements'in typewriters and particularlyto the ribbon I attachments thereof.

j My object is to produce a means for attaching and detaching ribbons toand from typewriters without annoyance or delay or soiling theoperators. hands. Also to produce a reel attachment which. Will permitof cleanliness in. changing old .and worn out ribbons .fornew and forexchanging one color or style 25. of ribbon for another, or for removingthe ribbon as in mimeograph work. This object I accomplishb means of aremovable flange on the reel an a slot split in the hub for receivingthe ribbon; also by such other and further construction as will appearby a perusal of the following specification and claims.

In the drawings similar characters of reference indicate correspondingparts in the several-views.

Figure 1 designates the ribbon movement ofa typewriter showing myimproved device installed thereon. Fig. 2 is a top plan view of a ribbonguide. Fig. 3 is a front elevation of said-guide, while Fig. 4 is a sideelevation Fig. 5 is a top lan view of a ribbon reel cup. Fig. 6is a si eelevation'of said on Fig. 7 is a top plan view of a ribbonree spindle orhub. Fig. 8 is a side elevation of the same. Fig. 9 is a top plan viewFig. 10 is an end clcvation of-a reel. Fig. 11 is a top plan view of aremovable reel flange. Fig. 12 is a side 'elevation of a pair oftweezers.

Referring to the numerals on the drawing 1 designates a fragmentaryportion of a type-writer showing the ribbon attachment thereon.

2 designates the reel cup formed with a passageway 3 for the passage ofthe ribbon out of said 0111),81 guide member being formed at the innerend of said passage, said guide 'structed as follows:

member being,composed of a strip of steel 4. secured to sideof cup andextending upward and having a bent over ortion Sleaving a spacetherebetween for t e insertion of the rlbbon, said guide being soarranged as to lead the ribbon out from the cup at an angle of thirtydegrees outward from a right line drawn from extremityof radius, fromcenter of cup to point of lead from cup. Arranged in said cups are myimproved reels con- 6 designates the hub or spindle having a lower fixedflange 7 attached thereto. Said hub is'provided with a slot 8 cut in oneside thereof the upper end of said slot being open for the purpose aswill appear. upward from the to thereof for the purpose of receiving areel as will appear. In the top of said hub 6 are struck in V-shapedgrooves 10 the same extending radially in respect to the center of saidhub. 11 designates a removable flange rovided with a slot 12 adapted topermit t 1e said flange to slip under the flange 9, said slot 12enlarging into a slot 13 for the purpose of permitting the insertion ofthe flange over the flange 9 to permit the same to be slipped thereunderas escribed. Outward from the slot 12 are struck out V-sha ed springclips 14 adapted to engage with tie grooves 10' thus holding the flangeon the said hub 6. I also provide a ribbon guide for guiding the ribbonin front of the type at the oint of contact, consisting of a main stainard 16, the same having a bifurcated end '17, the bifurcations thereofbeing provided with arms 18 having bent over ends 19 forming guides forthe ribbon. The construction permitsof an easy adjust ment of the ribbonin the shortest possible time.

In using the device when it is desired toexchange an old ribbon for anew one the Said hub also has a flange 9 held slitted portion isinserted in the slot 8, the

other remaining outside, thus forming a lock for said ribbon, B., or asmall piece of metal may be attached to the end of the ribbon having abent ortion to facilitate inserting the ribbon in t e slot 8 and roventits slipping through the slot 8. he flange 11 is then inserted under theflange 9 as-described, the spring clips 14 fitting into the grooves 10and thus locking said ilaiwe on the hub. To

msert the ribbon in the ribbon guide, Fig. 3,.

' der the bent over: ends 19.

it is only necessary to place 'a fold of the rib-,

bon over the bifurcated'end 17, with a penoil, etc., when u on, turningone of the reels proper place unthe ribbon will s ip into its I The"ribbon" guides described irnpart an even and free motion to the ribbon.Twezers 20 may be used in handling the ribbon;
